I was recently reading Stanley Hauerwas' book "Resident Aliens" and he made the point these qualities aren't natural for human beings. This, Hauerwas says, is the point. God is merciful. God is meek. God hungers and thirsts for righteousness. God is a peacemaker.
Our problem is when we think about God, we don't think of him in these terms. We envision God as bold and proud, looking to find justice - at all costs. We think God actually cares about what people think about him, that he has an image to keep. The matter of the fact is that, this is not who God is. God is willing to humiliate himself, looking to humble himself. God in the Bible continually goes out of his way to allow humans, though we don't deserve it, to have freedom to do what we want.
If you want to know who God is, read Matthew 5-7
